We show that solving jigsaw puzzles requires Θ(n ) edge matching comparisons, making them as hard as their trivial upper bound. This result generalises to puzzles of all shapes, and is applicable to both pictorial and apictorial puzzles.

This study aims to find out how the influence of Jigsaw learning strategies on students' metacognition development. uses a quantitative method by distributing questionnaires students in both classes, namely control and experiment. The population this was 56 students. From study, it found that use type model MA could provide an increase metacognition. is indicated average number treatment class ...

An algorithm for assembling square jigsaw puzzles is presented. We commence by introducing criteria that govern the selection of proper jigsaw puzzle solving method for a given application. Our algorithm uses the gray level profiles of border pixels for local matching of the puzzle pieces. Unlike the classical best-first search, the algorithm simultaneously locates the neighbors of a puzzle pie...

BACKGROUND This three-part study examines previous clinical impressions that people with Prader-Willi syndrome have unusual jigsaw puzzle and word search skills. RESULTS Children with Prader-Willi syndrome showed relative strengths on standardized visual-spatial tasks (Object Assembly, Triangles, VMI) in that their scores were significantly higher than age- and IQ-matched peers with mixed men...

This paper presents a novel encryption-less algorithm to enhance security in transmission of data in networks. The algorithm uses an intuitively simple idea of a ‘jigsaw puzzle’ to break the transformed data into multiple parts where these parts form the pieces of the puzzle. Then these parts are packaged into packets and sent to the receiver. A secure and efficient mechanism is provided to con...
